At the moment we have a once a day 5 minute period where ds has to do all his talking in his head. This is about all he can manage and once the 5 minutes are up he is practically bursting to spill all those silent thoughts out again. My aim is to increase the number of times he needs to do this or the length of time he does this for but I think this goal is more about my needs than his. I have to say that the other several hours of play by play commentary with constant 'mum' interjections to make sure he has my attention are getting a little wearying. How do you deal with it and do you moderate the obsession at all. DS has very specific sequences of setting up army formations or camps and then commentating on each stage of the building and operation of the "troops" he doesn't like you to engage in the conversation ie won't answer questions about what he is doing but does require your undivided attention to what he is saying.
I am finding it hard to deal with at the moment. As I type this he is setting up a very complicated scenario with the blocks and getting very annoyed when I look down at the computer screen instead of at what he is doing and saying.
